How to Download Redis Using wget
Redis is an open source, in-memory, key-value data store that is used as a database, cache, or message broker. It is fast, reliable, and scalable because it saves data in RAM rather than on a disk or SSD. It supports various data types like strings, lists, sets, bitmaps, and streams.
wget is a command-line utility for downloading files from the web. It supports HTTP, HTTPS, and FTP protocols and provides many options for customizing your downloads. You can use wget to download multiple files, resume interrupted downloads, limit the bandwidth, mirror a website, and more.

In this article, you will learn how to use wget to download Redis from its official website. You will also learn how to verify the integrity of the downloaded file and how to compile and install Redis from source.
How to Install wget on Different Operating Systems
wget is available for most operating systems and platforms. Here are some instructions on how to install it on Linux, macOS, and Windows.
Linux
Most Linux distributions come with wget pre-installed. To check if you have wget on your system, open a terminal and type wget. If you see wget: missing URL, then you have wget installed. Otherwise, you will see wget: command not found.
If wget is not installed on your system, you can use the package manager of your distribution to install it. For example, on Ubuntu or Debian-based systems, you can run:
sudo apt install wget
On CentOS or Fedora-based systems, you can run:
sudo yum install wget
macOS
macOS does not come with wget by default. However, you can install it using Homebrew , a popular package manager for macOS. To install Homebrew , follow the instructions on its website . Once you have Homebrew installed, you can run:
brew install wget
Windows
Windows does not have a native version of wget. However, there are several ways to use wget on Windows. One way is to download a binary version of wget from [27]( and install it on your system. Another way is to use Cygwin , a software that provides a Linux-like environment on Windows. You can install Cygwin from its website and then select wget from the list of packages. A third way is to use Windows Subsystem for Linux (WSL) , which allows you to run Linux commands and applications on Windows 10. You can enable WSL from the Windows Features dialog box and then install a Linux distribution of your choice from the Microsoft Store . Once you have WSL set up, you can use wget as you would on Linux.
How to Use wget to Download Redis
To use wget to download Redis , you need to know the URL of the file you want to download. You can find the latest stable version of Redis on its download page . At the time of writing this article, the latest stable version is Redis 5.0.7.
The basic syntax for using wget is:
wget [options] [url]
The options are optional parameters that modify the behavior of wget . The url is the web address of the file you want to download.
For example, to download Redis 5.0. 7, you can run:
wget
This will download the file redis-5.0.7.tar.gz to your current directory. You can use the -O option to specify a different output file name. For example, to save the file as redis.tar.gz, you can run:
wget -O redis.tar.gz
You can also use the -P option to specify a different output directory. For example, to save the file in the /tmp directory, you can run:
wget -P /tmp
wget will show you the progress of the download, including the file size, download speed, and estimated time remaining. Here is an example of the output:

How to Verify the Integrity of the Downloaded File
Before you compile and install Redis from source, it is a good idea to verify the integrity of the downloaded file. This will ensure that the file has not been corrupted or tampered with during the download process.
There are two ways to verify the integrity of the downloaded file: using SHA-256 digests or using GPG signatures.
Using SHA-256 Digests
A SHA-256 digest is a string of hexadecimal characters that represents the unique fingerprint of a file. You can compare the SHA-256 digest of the downloaded file with the one provided by Redis on its website . If they match, then the file is intact and authentic.
To calculate the SHA-256 digest of the downloaded file, you can use the sha256sum command on Linux or macOS, or the CertUtil command on Windows.
For example, on Linux or macOS, you can run:
sha256sum redis-5.0.7.tar.gz
This will output something like this:
f0f0f544fe70ed3626dbbfb933d4d66c65a9a40518f8683aae9a9e6b790894ad redis-5.0.7.tar.gz
On Windows, you can run:
CertUtil -hashfile redis-5.0.7.tar.gz SHA256
This will output something like this:
SHA256 hash of redis-5.0.7.tar.gz: f0 f0 f5 44 fe 70 ed 36 26 db bf b9 33 d4 d6 6c 65 a9 a4 05 18 f8 68 3a ae 9a 9e 6b 79 08 94 ad CertUtil: -hashfile command completed successfully.
You can then compare the output with the SHA-256 digest provided by Redis on its website . If they match, then the file is verified.
Using GPG Signatures
A GPG signature is a digital signature that proves that a file was signed by a trusted party using a private key that matches a public key . You can verify the GPG signature of the downloaded file with the public key provided by Redis on its website . If the signature is valid, then the file is authentic and untampered.
To verify the GPG signature of the downloaded file, you need to have GPG installed on your system and import the public key of Redis. You can download the public key from [26]( and save it as redis.asc. Then, you can run:
gpg --import redis.asc
This will import the public key into your keyring and output something like this:
gpg: key 4B8EC3BA: public key "Salvatore Sanfilippo " imported gpg: Total number processed: 1 gpg: imported: 1 (RSA: 1)
Next, you can download the GPG signature of the file from [25]( and save it as redis-5.0.7.tar.gz.asc. Then, you can run:
gpg --verify redis-5.0.7.tar.gz.asc redis-5.0.7.tar.gz
This will verify the signature and output something like this:
gpg: Signature made Tue 25 Jun 2023 11:32:59 AM UTC using RSA key ID 4B8EC3BA gpg: Good signature from "Salvatore Sanfilippo " gpg: WARNING: This key is not certified with a trusted signature! gpg: There is no indication that the signature belongs to the owner. Primary key fingerprint: C7A9 8D78 4CBB FBCF A4E2 C64F E7A8 3D2A 4B8E C3BA
The output shows that the signature is good, meaning that it matches the file and the public key. However, it also shows a warning that the key is not certified with a trusted signature, meaning that you have not verified the identity of the signer. You can ignore this warning if you trust the source of the key.
How to Compile and Install Redis from Source
Once you have downloaded and verified the file, you can compile and install Redis from source. This will allow you to customize your installation and use the latest features of Redis.
Prerequisites and Dependencies
To compile and install Redis from source, you need to have some prerequisites and dependencies on your system. These include:
A C compiler, such as gcc or clang
A GNU make tool
A tar utility to extract the tarball
An optional dependency is jemalloc , a memory allocator library that improves the performance of Redis. If you don't have jemalloc installed, Redis will use the default libc allocator.
You can check if you have these tools on your system by running their commands with the --version option. For example, to check if you have gcc , you can run:
gcc --version
If you don't have these tools on your system, you can install them using your package manager or download them from their websites.
Extracting the Tarball and Running Make
To extract the tarball, you can use the tar command with the -xzf options. For example, to extract the file redis-5.0.7.tar.gz, you can run:
tar -xzf redis-5.0.7.tar.gz
This will create a directory called redis-5.0.7 with the source code and other files.
To compile Redis , you need to change into the directory and run the make command. For example, to compile Redis 5.0.7, you can run:
cd redis-5.0.7 make
This will compile Redis using the default settings and create several executable files in the src directory, such as redis-server, redis-cli, redis-benchmark, and others.
Installing Init Scripts and Configuration Files
To install Redis on your system, you need to copy some files to their appropriate locations. You can use the make install command to do this automatically, or you can do it manually.
The files that need to be copied are
